MOLD FOR BRICK AND RE-PRESSING MACHlNES.

SPECIFICATION forming part of Letters Patent No. 301,131, dated July Il, 1884.

Application filed December 2l, 1883. (No model.)

.To @ZZ whom, may concern:

Beit known that I, Girone-E H. KUNTZ, a citizhen of the United States, residing at Belleville, in the county of St. Clair and State of Illinois, have invented a new and useful In1- proved Mold for Brick and Ito-Pressing Ma chincs, of which the following is a specification.

The objects of myimprovements are to press orre-pressbrickuniformlyastosize,shape,with well-defined edges, sides, corners, Src.; also be capable of removing the iinished brick from the mold without incurring the disadvantages arising from friction, warping, or expansive action, and otherwise to render the operation of the entire mold double-acting, so that while one brick is being acted upon by the rc-pressing plunger the releasing-plunger can also be Operated to release the finished brick preparatory to receiving a new brick, and changing the position of the molds by a turn motion upon its axis. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- v Figure 1 is a plan view (with the top removed) of the entire mold, to better show the reciprocating inside frame, its eccentric connection to the central axis or shaft, and the consequent enlargement of the one mold-cham ber for purposes of releasing the finished brick, while the opposite mold-chamber is closed as to area, size, Ste., and contains the brick to be re-pressed. Fig. 2 is a vertical sectional elevation of the entire re-pressing machine, the section being taken on line 2 2 of Fig. l. Fig. 3 is a front elevation, and Fig. 4 a rear elevation of the entire machine.

A represents the frame of the machine.

B represents the top portion or bed, upon which the entire mold is mounted.

O represents the entire mold, the bottom frame ol' which is made to form the chambers c c', in which the respective sub-plungers D D are fitted to operate, as indicated in Figs. 2, 3, 4. In line of action with the sub-plungers D D (which serve, respectively, as rel-easing and repressing plungers, as will hereinafter appear) the chambers c cconstitute also the open moldchambers proper, in which the respective operations of pressing the brick and releasing the finished brick are done iu alternate manner.

These n1oldchambers c c are rectangular shaped and oppositely related, one being at each end of the mold C, in manner shown in Figs. l and 2. The outer side and end walls (marked d d) of moldframe C constitute the onehalf side and end wall ofthe molds cc. (Sec Figsl, 2,where it will be seen that the line of division is the diagonal through the rectangular shape of each mold-chamber.) The remaining duplicate side and end walls, (marked d2 di) however, form part of a movable frame, E, which operates within the mold-frame C, as shown, the purpose of so dividing the walls of each mold-chamber being to enlarge the area of the one chamber at the time the re-pressed brick is to be released for removal, 85e., also at same time to make smaller the other mold, and adapt to the determined area, size, Snc., in which the brick is to be re-presscd.

F is a central bolt or axis having an enlarge ment at fand the eccentric at f The said axis passes through the central collar, f", ofthe mold O, and by means of the nut-plate at f3 and screw-nut at -f3 the said moldi is capable of being turned top of the machine. (See Figs. 1, 2, 3, 4L.)

Surrounding the eccentric f are two sliding blocks, f 4 f 5, and these play within the squareshaped frame f, which forms part of the inside or'reciprocating frame, E. (See Figs. l, 2.) As apparent, in turning the entire mold O on its axis, this, by its eccentric, imparts a re- I ciproeating slide motion to the inside frame, E, and this movement, by means of the seetional walls 22 da, causes, respectively, the en largement of the one mold, while decreasing or making smaller the area of the opposite mold-chamber- Also, in so turning the entire mold, it carries with it (in the bottom of each moldchamber) the sub-plan gers D D', an d thus in alternate manner each of these plungers, together with each of the mold -chambers c c, can be brought in line of action with the main re-pressing and releasing plungers G G of the machine. Both the main plungers G G opcrate vertically, being reciprocated in the frame of the machine by separate handle and treadle attachments. (See Figs. 2, 3, lI.) .The re-pressing plunger G is pivoted to the kneelevers g g', the cam-faced meeting ends of which are pivoted to a T-lever, g2, that in turn is piv- IOO oted to the hand-lever H, having its fulcrum ath, its short arm h in line of engagement with the outer arm of the foot-lever I, which is fulcrumed at 13, and whose inner arm, t', is in turn pivoted to the lower extremity of one of the knee-levers, as shown in Figs. 2, 3. A pull outward on the hand-lever draws the kneejointed levers together in a vertical line, and thrusts the re-pressing plunger G upward, and

Io in so doing also raises the sub-plunger that is in line of action and presses the brick. By releasing the hand-lever the yplungers drop and the parts assume their original position. With the same hand and knee-j ointed levers the top i5 platen, J, is operated, it being connected by the side rods, j j', having their lower ends pivoted at .72 js to the lower transverse rod, ji, while the upper ends of said side rods connect to a yokeframe, J', that carries the platen J, as shown 2o in Figs. 2, 3. This yoke is sufficiently large to permit the corners of the mold C to turn free,

as indicated. In raising the re-pressing plunger, therefore, by the said hand and knee levers, the yoke and its platen J are drawn downward, so that the latter with the same force plunger the platen J is raised clear of the mold. 3o (See Fig. 2.)

The releasing-plunger G, by the intermediate arm, K, is pivoted to a foot-treadle, K', which, when operated, can raise or lower the said plunger for purposes of lifting the iinished 3 5 brick.

In dividing the plungers into sub and main plungers the former can be turned with the 'mold without interference to the remaining part of the machine, and when brought in line 4o of action with the main plungers be readily operated, as just stated.

In the complete operation of the machine the finished brick is shown in the mold having its area enlarged by the clearance indicated by x in Figs. l and 2; hence it is ,ready for removal and preparatory to placing a new brick inthe same mold. In the opposite mold (see Figs. l and 2) the brick to be re-pressed is in line of action with the platen and re-press- 5o ing plungers. When this brick has been repressed, the mold C is turned upon its axis, so as to bring the fresh brick in line under the platen, and the repressed brick in line ofthe releasing-plunger. It is this turn movement of the mold that releases the `nished brick by enlarging its mold-chamber to the extent of the clearance m, and gives the opposite mold-chamber the proper dimension to suit the brick to be repressed.

I am aware that brick-machines have been 6o made in which the clay is taken from the bank, passed into molds which can be re volved on an axis, and coacting ascending and descending plungers press the brick, a further ejector or releasing-plunger releasing 6 5 the finished brick, nor do I claim such.

What I claim isl. In a brick-machine, the combination of the mold C, forming part of which are the outer side and end walls d cZ, that constitute 7o one half of the molds or chambers c c', their opposite and remaining half or side and end walls Z2 d3 forming part of an inside reciprocating frame, E. by means whereof the revolving of the said mold C reciprocates its inside frame, and this by its walls enlarges or contracts vthe area of the molds or chambers, substantially as and for the purposes set forth.

2. In a brick-machine, the combinationv of the moldframe C, the mold-chambers c c', 8) carrying the sub-plungers DD. said chambers further composed of the diagonally-divided side and end walls, d d d2 di, of which the two former walls or sides formpart of the said mold-frame C, while the two latter sides form part `of an inside frame, E, having square frame f, the sliding blocks f4 f5, the central bolt or axis, F, having eccentric j', andthe bed B of frame A, carrying a vertical releasingplunger, G', substantially as and for the pur- 9o poses set forth.

3. In a brick-machine, the combination of the mold -frame C, the moldchambers c c', carrying the sub-plungers D D, said chambers further composed of the divided side and end walls, cl d d2 d3, of which the two former form part of the mold-frame C, while the two latter walls form part of an inside frame, E, having square frame f6, the sliding blocks f4 f5, the central bolt or axis, F, having eccentric f', the bed B of frame A, carrying a vertical coacting re-pressing plunger, G, and platen J, substantially as and for the purposes set forth.

In testimony of said invention I have hereunto set my hand.
